Purchase price: $375,000 Cash invested: $30,000 This was a 2 unit that I purchased in 2016 for $375K.

There are no restrictions preventing out-of-state investors from purchasing rental properties in Texas—these investors enjoy the same opportunities as Texas residents.Additionally, the financing restrictions you mentioned don’t align with reality.

If you are looking to just calculate profitability, set how much profit you want to make then:ARV - Purchase Costs - Holding Costs - Selling Costs - Desired Profit - Rehab Budget (including contingency) = Maximum Allowable OfferIF you cannot calculate those numbers, a spreadsheet isn't going to help you. 

Case Study: A Successful Joint Venture in Real Estate - An investor identifies a distressed property with high potential but lacks the funds to purchase and renovate it. - The investor partners with a private lender who provides the capital.

It may be a little scary but if you go higher on your purchase price, 400k and up. 

Quote from @Laurens Van swol: We are exploring the possibility of purchasing an investment property in Florida.

Process is simple. 1. purchase contract2. send contract to title company3. bring cash to closing and you're done

Thanks in advance.I am guessing you have an FHA loan on the house and the new buyer will be purchasing with an FHA loan?
